hi, I'v got some data attached as apx.csv. It shows the relationship about a kind of enzyme and the temperature. "yhf" and "xbt" are 2 kind of cowpea. "apx" is the kind of enzyme and "low" means the lowest temperature intraday. "date" means 1 to 121 days.
What I want to show with it is how is "apx" changes with "low" on 2 kind of cowpeas. And "date" is better not missing in graph. I have made one by ggplot2 using apx2.csv (reshaped by melt). apx<- read.csv("apx2.csv") p<- ggplot(apx, aes(x= dat, y=apx, colour= factor(var))) p + geom_line()+facet_wrap(~var,ncol=1, scales= "free_y") The graph is NOT good enough. It is not easy to find the relationship between "apx" and "low". How could I do better? Is it possible to show "low" data as graph background color changing with "date"? Thank you. -- Stand Alone Complex
